Research on Spatial Cooperation of Urban Bike-Sharing Systems in Nanjing Based on Multivariate Data

Under the free development environment, public bicycles (PB) and free-floating bike sharing (FFBS) often overlap for service. This study explores the feasibility of spatial cooperation of the two systems in Nanjing based on multivariate data. The FFBS trips are divided into similar and supplementary trips for PB, and used to compare with PB for spatial usage characteristics. And the surrounding feature differences of PB and FFBS dominant stations are analyzed through 13 factors with GIS. The results indicate the dissimilarity between the two systems. And this study proposes to place major FFBS in the area with dense roads, large demand sources, and scattered location, especially the area with more entertainment venues. The findings provide a scientific basis for the measures for spatial cooperation, which is of great significance to the sustainable development of urban bike-sharing systems.
